Summer CO2 evasion from streams and rivers in the Kolyma River basin, north-east Siberia

, 2013
Inland water systems are generally supersaturated in carbon dioxide (CO2) and are increasingly recognized as playing an important role in the global carbon cycle.

Fast perceptron decision tree learning from evolving data streams

, 2010
Mining of data streams must balance three evaluation dimensions: accuracy, time and memory. Excellent accuracy on data streams has been obtained with Naive Bayes Hoeffding Trees—Hoeffding Trees with naive Bayes models at the leaf nodes—albeit with ...

Potential Health Implications of Heavy Metal Contamination of Streams Near Quarry Sites in Akamkpa, Cross River State, Nigeria

Studia Ecologiae et Bioethicae
This study examined the potential health implications of heavy metal contamination of streams near quarry sites in Akamkpa, Cross River State. Three rural communities were selected (Awi, Nsan, Old Netim) and three streams near operating quarries were ...

On Streams of Events and Mixtures of Streams

Journal of the Royal Statistical Society Series B: Statistical Methodology, 1966
Summary Distribution functions for streams of events (and, in particular, for the length of the interval “between successive events”) are defined within the framework of the theory of Khintchine (1955). Relationships such as that between the distributions for the length of an “arbitrary interval” between successive events, the interval ...

Fostering Innovation: Streamlining Magnetocaloric Materials Research by Digitalization

Advanced Engineering Materials, EarlyView.
Magnetocaloric cooling (MCE) is an environmentally friendly refrigeration method with great potential. Optimizing MCE materials involves the preparation and screening of large quantities of samples, which in turn generates a large amount of data. A digitalization approach is presented that uses ontologies, knowledge graphs, and digital workflows to ...

Epilithic diatoms (Bacillariophyceae) from running watersin NW Iberian Peninsula (Galicia, Spain)

Anales del Jardín Botánico de Madrid, 2017
A catalog of Bacillariophyceae for the rivers of NW of Spain is made for the first time. It includes a re-examination of the taxa reported in previous publications, taxa cited during the last years of the rivers of the Galicia-Costa Hydrographic ...

Periphyton growth on allochthonous input in streams may lead to higher individual growth rates of the invasive New Zealand mud snail (Potamopyrgus antipodarum)

Journal of Limnology, 2023
The aquatic, invasive New Zealand mud snail (Potamopyrgus antipodarum) exploits a variety of food sources. Here we examine the change in growth of snails that fed on periphyton colonizing leaf litter, wood, rock, and a control.

Stream Types [PDF]

Proceedings of the ACM on Programming Languages
We propose a rich foundational theory of typed data streams and stream transformers, motivated by two high-level goals. First, the type of a stream should be able to express complex sequential patterns of events over time.
